That doesn’t sound right… maybe they’re doing other things in the background, in addition to that 1 blog post? You should ask them for more details about their completed work and strategy + action plan once the “update volatility” settles.

There’s always Google volatility, updates, chatter, etc. The fundamentals never really change (quality content, technical SEO, and links).

They should be able to tell you what on-page optimizations they’re planning on, keywords they will be targeting, PR + link building strategy, areas for improvement, etc.
